BRACELET.

Application filed J'uly 12, 1926. Serial rNO. 121,808.

This invention .relates vto -an improvement in the construction' otchains or bracelets formed of a pluralityfoffconnected extend- -iblelinks; and the object otrthis invention -is the construction ot suchachain or bracclet which compriscsa scriesot' box links-f connected bytrame links, each frame link vbeing mounted to slide withinits box .linkand a spring being :provided fin each box -link acting upon it andtheframe link to pressfboth toward contracted position.

A. further-object of the vinvention is the provision Y of rsuch anextendible bracelet in which -the box links each have .a lresilient wallto which oneend of a 4frame-shaped connecting flink insthe next adjacentbox link is detachably connected.

lilith theseand other objectsin view, the inventionconsistsY of certainnovel features of construction, as will be more ,fully described, yandparticularly pointed out 1n the appended claims.

In the accompanyiuig` dnawings:

tis found in the practical vconstruction and Operation of extendiblebracelets or chains of this character, ot advantage in some instances,to Jform the links very thin, whereby they will lie flat and close tothe embodiment of my invention and showing one construction of bracelet,by whichthese r.advantageous results may be obtained.:-

end wall 17 of the next adjacent box link. This frame link or yoke linkmay be formed of wire bent into shape or it may be blanked from sheetstock without a joint,

if desired and open both top and bottom.

The links are detached one from the other by swinging the two adjacentbox links at an angle to each other and springing outwardly or liftingup the end wall and its lip 18 slightly to permit the end bar 21 of the:trame link to be passed thereover.

At the timethis frame link or yoke v"is positioned in the box link andbefore the latter is entirely closed, a coiled spring 22 is alsopositioned in this box link to act between the end bar 23 of the framelink and the end wall 16 or the box link serving to press the frame linktowards housed or contracted position in its box link and at the sametime permit the maximum amount o'l expansion between the links of thebracelet so that it may be iiexibly extended suiticiently to be passedover the hand of the wearer when desired.

In some instances, instead of forming the bottom wall 1li of a width toVlie upon the edges oi the side walls 15, as illustrated in Figure 5, Imay form the bottom wall 24-,"as illustrated in the modification inFigure 10, narrower to fit between the side walls 25 permitting` it tobe depressed slightly and cooperate with the resilient end wall 1i topermit the frame link or yoke to be more readily detached from its boxlink by springing this end wall 1T with its lip 18 outwardly and alsothis rear wall 24- slightly inwardly.

My improved bracelet is extremely simple and practical in construction,is etlective in its operation, presents abroad surface to be ornamentedwhen desired, may be made very thin to lie close against the wrist ofthe wearer, may be manufactured at the minimum cost, and is veryhandsome and attractive in appearance.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim:

1. An expansible bracelet comprising a series of outer box links eachhaving top, bottom, side and end walls, yoke links substantiallyrectangular in shape and one being partly housed in each box link andembracing the end wall of the box link partly housing it and the endwall of an adjacent box link, and a spring acting between said 'yokelink and the box link in which it is housed whereby the bracelet may beextended in the direction vof its length by yieldingly sliding the yokelink out of the box link, one or" the walls of the outer box link beingresilient to permit flexing for detaching the yoke link from the endwall of the said adjacent box link.

2. An expandible bracelet comprising a series of box links, each havingtop, bottom and side walls and a resilient end wall, a frame linkpartially housed and slidably mounted in each of said box links andhaving one end connected to the resilient wall of the next adjacent boxlink which may be detached therefrom by flexing the resilient end wall,and a spring in each box link pressing its frame link to contractedposition therein.

An expandible bracelet comprising a series of outer box links, eachhaving top, bottom, side and end walls, an inner yoke link slidable ineach box link and having an end portion located outside of the box linkand engaging the end wall of the next box link, and means to permit aseparation of the engaged end wall and its adjacent wall for detachmentof the yoke link therefrom.

el. An expandible bracelet comprising a series of outer box links eachhaving top, bottom, side and end walls, an inner yoke link slidable ineach box link and having an end portionv located outside of the box linkand engaging the end wall of the next box link, said engaged end wallbeing resilient and having a portion separable from the other wall topermit detachment of the yoke link therefrom.

5. An expandible bracelet comprising a series of box links, each havingtop, bottom,

side and end walls, one of the end walls being resilient and having alip portion overlapping its bottom wall, a frame link slidable in eachbox link and having one end detachably connected to the resilient wallof the next adjacent box link, and a spring in each box link actingbetween its opposite end wall and the housed end of its frame linkpressing these links toward contracted position.

In testimony whereof I a'liix my signature.
